PINTLE-INSERTING IMACHINE.

original application filed July 29, 1919, Serial No. 314,013. Dividedand this application filed June 22,

To all whom it may concern:

Be it known that I, CHARLES V. Srrnon- LAND, a citizen of the UnitedStates, and resident of lVinston-Salem, in the county of 6 Fors'yth andState of North Carolina, have invented certain new and usefulImprovements in Pintle-Inserting Machines, of which the following is aspecification.

My invention'relates to a hinge forming 10 machine, and especially to amachine for attaching hinge pintles to sheet metal blanks.

It is particularly applicable to machines of the type. shown in theUnited States patent to Richter, No. 1,096,863 issued May 19, 1914, theinvention set forth in this specification being a division of thatdisclosed in my copending application Ser. No. 314,013, filed July 29,1919, 1,413,627 dated April 25, 1922.

Machines of this general nature handle a sheet metal blank, which mayeither be flat or formed into any other shape, the preferred typeoperating on flat blanks. The blanks are provided with suitableprojecting elements, which the machine wraps about a wire pintleautomatically out off and brought into engagement with the blankelements. By this operation the pintle is permanently mounted on theblank with spaces between the blank elements where the pintle may beengaged by the similar elements of the other hinge member.

Machines of this type have heretofore been operated as separate units,the pintled blanks being discharged by the machine into any suitablereceptacle and delivered to the operator of the machine which forms theblanks into metal container bodies.

A principal object of my invention is to provide a. pintle insertingmachine which will deliver its product directly to the body formingmachine. A corollary object is to provide means for insuring theaccurate registration of the delivered blanks in proper position on thebody forming machine to be engaged by the operating mechanism of thelatter.

Another object is-to so arrange and construct the parts of a pintleinserting machine of the type indicated that it can read ily be actuatedby the driving mechanism now Patent No,

Serial No. 479,585

of the body forming machine, and preferably so that the pintle formingmachine is mounted on the body former substantially as an attachmentthereto, with the obvious resultant saving in floor space, constructionexpense and operating difiiculty.

Other objects and advantages of my invention will be apparent from thefollowing description, taken in connection'with the accompanyingdrawings, in which:

The single figure is a front elevation of the entire machine mounted ona standard type of body forming machine, parts being broken away.

The form of pintle inserting machine disclosed in the preferred formillustrated is described in detail in my above mentioned Patent No.1,413,627, and is of the general type shown in the Richter patent. As mypresent invention relates to the combination of this machine with thebody former, I will set forth merely the important features of thepintle inserting mechanism, reference being made to my abovementionedpatent and the Richter patent for a detailed description of the parts.

The fiat metal blanks 25, preferably lithographed, are fed into themachine by hand. a stack of blanks being shown on the plat form 42 atthe left of the machine. They are placed by the operator on areciprocating feed plate or bar provided with spaced feed dogs 48 whichare spring pressed upwardly the outer end of each dog projectingslightly above the upper surface of the feed bar and engaging the rearedge of a blank and advancing it during the forward stroke. of the feedbar from left to right. On the return of the feed bar the blanks areheld in stationary position by various friction devices, the dogs 48sliding under the blanks. The feed bar is reciprocated by a rock arm 36pivoted on the frame and connected to the feed bar by a link 35, arm 86being oscillated by pitman 37.

While in stationary position, the edges of the blanks are first cut toshape by the cutter 61, and then provided with pintles attached theretoby a pintle inserting mechanism, the main operative portion of which isindicated at 66, this portion being adapted to engage tongues onsuccessive blanks with wire pintles. The cutter 61 and pintle applyingmechanism 66 are mounted on a vertical reciprocating ram 50 connected toa crank on shaft 54, so that a blank is cut away and the successiveblank provided with a pintle at each descent of ram 50, while the blanksare held in stationary position during the return of feed bar 33.

The machine is also provided with a device, indicated generally at 100which is arranged to feed forward intermittently a continuous wire toprovide suitable pintle lengths, one of which is cut off and engaged bythe pintle forming element 66 at each descent of the ram 50. The wirefeeding device 100 is operated by a pitman 93.

The body forming machine includes a frame 23 carrying a drive shaft 42,and provided with a guideway or channel 1.2 1 along which the pintledblanks are advanced by suitable mechanism into engagement with thedevices which form therefrom container bodies.

1 have so constructed and arranged the pintle inserting machine that itwill deliver blanks to the feed channel 12% of the body former in properposition for operation thereby. I have accomplished this result bylocating the pintle inserting machine in po sition so that the feed bar33 extends substantially at right angles to the feed channel 124i andinto juxtaposition thereto, so that the last feeding movement to theright i1 parted to a blank by the feed bar will locate it withconsiderable accuracy across channel 124. With the type of body formernow in general use and illustrated in the drawing, the blank will bepositioned properly for engagement by the operating mechanism of thebody former.

I may also provide suitable mechanism for insuring the accurateregistration of the blanks on the body machine feed, so that thecarriage of the latter will engage them without any manipulation by theoperator. This mechanism may consist of a lever 119 pivoted on a bracket120 mounted on the bed of the body former, one end of the lever carryinga roll 121 engaging cam slot 122 in cam 123. The opposite end of lever119 carries positioning plate 124 mounted adjacent to the end of thepintle machine feed and shaped to guide and hold the pintled blank inaccurate position on the feedway of the body machine. It will be notedthat the positioning plate 124 is so contoured and particularly isrecessed at its lower face, so as to clear the carriage of the bodyformer which travels along the feedway 124 conveying the successivepintled blanks into the body forming mechanism.

I also provide means whereby the operation of the pintling machine andthat of the means for registering the blanks on the body former aresynchronously operated. In general I accomplish this object by providingdirect connection between the driving mechanism of the pintling machineand that of the registering device. In the form shown, I have alsoprovided a simple driving construction for all of the parts indicated,which further assures complete synchronism between the pintling machineand the body former. I have accomplished this object by driving all ofsuch devices from a vertical shaft 10 suitably driven from the shaft l2of the body former. Pitman 87, which operates the feed bar, is actuatedby cam 39; pitman 93 operating the wire feed is actuated by cam 97; andboth of said cams, together with cam 123 which operates the blankregistering device, are directly mounted on shaft 40. The latter shaftalso drives, by suitable gear connection, shaft 54 which operates theblank cutting and pintle attaching devices. Obviously various otherdriving arrangements may be employed, the one illustrated beingprimarily advantageous because of its simplicity and convenientarrangement.

The operation of the machine is as follows. As heretofore indicated,successive blanks 25 are located on the left-hand end of feed bar 33,which shifts the successive blanks step by step toward the right, theblanks being excised when under the cutter 61, and provided with pintleswhen under the pintling device 66. From the latter station they areadvanced step by step until the final impulse from feed bar 33 projectsthem into position across the feed channel 12 i of the body former.During the latter motion the registering plate 124- is maintained inelevated position by cam 124; but as soon as the blank is located on thebody former channel the registering plate 124i is depressed, positioningthe blank accurately on said channel and preferably maintaining it insuch position until the body former carriage has engaged the blank andadvanced it along the channel. The registering plate 12a is thenelevated to receive the next blank, the feed of the pintle insertingmachine being suitably synchronized. with that of the body former, as bydriving connections of the type indicated.

It will be apparent that substantial modiiications and changes may hemade in the various elements, and particularly in the type of mechanismemployed for inserting pintles in the blanks and for feeding themforward. My invention therefore is not limited to the particulararrangement shown, but may be substantially varied as indicated b j thescope of the following claims.
